Dances were stupid and people were stupid and dates were stupid and this whole thing was stupid. Cornelius was only even here to see just how stupid it all was, so he could revel in the knowledge of how stupid his classmates all were, and how much better he was than them. With their dancing and pashing and stupid outfits, it was all dumb. Only those who were too stupid to know better would be seen dead at something like this. Which was why he was here. To laugh at them.
It had nothing to do with spin the bottle, and definitely nothing to do with Vanity. Only a moron would even suggest as much. Cornelius had taken a spot a ways away from the door with a good view of it so he could watch everyone as they came and went, not just look out for Vanity. That said - radiant in bright pink, it was hard to miss her. She was the only bright spot in an otherwise dull crowd of idiots, dullest of all the idiot beside her. It was the bad boy appeal, he supposed. The glitz and glamour of having the worst, most worthless kid in fifth year on her arm. Cornelius was just mentally conjuring up a dramatic scenario where he swooped in and saved Vanity from her tedious date when his view was obstructed. He scowled as what's-her-name blocked his view, a pointless Gryffindor he had never bothered to get to know. "Excuse me, some of us are trying to see." He snapped. "Get your big head out of the way."
